Enhancement of the 7th & 8th cranial nerves

I have been suffering since January 1st with a severe headache which put me in the hospital for a few days. I have had 2 MRI and they claim they is nothing more they can do. As of Monday May 31st the pain has moved to the front of my brain, before it was always on the left side behind my ear. Every time I shook my head the pain would go away for a second then build up again. I have tried many different medications but as of todays date nothing takes away the pain. Before I could not stand or sit up because the pain was so bad I was bed ridden for a month and I got sick everyday. I want to know if anyone else has ever suffered this type of pain? I am 48 years old and have never really experienced pain like this nor had headaches before.
Please advise
Any information would be so helpful
Thanks again
Cathy
